Kristian Campbell was 2024’s prospect breakout. He shot through the minors and got an invite to spring training in 2025. He broke camp with the Boston Red Sox and even got a long-term extension.
In April, he looked like the early frontrunner for AL Rookie of the Year. He hit .301 with a .902 OPS and was named the AL Rookie of the Month while playing almost every day at second. Then things fell off a cliff.
Campbell hit just .134 in May and .205 in June while being the worst defensive second baseman in baseball. It resulted in him being sent down to Triple-A.
